Hello, This is the third version of this series adding writeback support to the VC4 display engine. This version is based on drm-misc-next and include a bunch of modifications to the core that I had to add to make it work on VC4. Not much has changed in this v3, just a few minor fixes/cleanup/rework and the addition of one patch to make commit->atomic_commit() optional. See the changelog in each patch you want more details. Regards, Boris Boris Brezillon (9): drm/atomic: Avoid connector to writeback_connector casts drm/connector: Pass a drm_connector_state to ->atomic_commit() drm/connector: Make ->atomic_commit() optional drm/vc4: Use wait_for_flip_done() instead of wait_for_vblanks() drm/crtc: Add a generic infrastructure to fake VBLANK events drm/atomic: Call fake_vblank() from the generic commit_tail() helpers drm/vc4: Call drm_atomic_helper_fake_vblank() in the commit path drm/vc4: Add support for the transposer block ARM: dts: bcm283x: Add Transposer block .../devicetree/bindings/display/brcm,bcm-vc4.txt | 6 + arch/arm/boot/dts/bcm283x.dtsi | 6 + drivers/gpu/drm/drm_atomic.c | 4 +- drivers/gpu/drm/drm_atomic_helper.c | 47 +- drivers/gpu/drm/vc4/Makefile | 1 + drivers/gpu/drm/vc4/vc4_crtc.c | 138 ++++-- drivers/gpu/drm/vc4/vc4_debugfs.c | 1 + drivers/gpu/drm/vc4/vc4_drv.c | 1 + drivers/gpu/drm/vc4/vc4_drv.h | 7 + drivers/gpu/drm/vc4/vc4_kms.c | 11 +- drivers/gpu/drm/vc4/vc4_txp.c | 477 +++++++++++++++++++++ include/drm/drm_atomic_helper.h | 1 + include/drm/drm_crtc.h | 23 + include/drm/drm_modeset_helper_vtables.h | 6 +- include/drm/drm_writeback.h | 6 + 15 files changed, 699 insertions(+), 36 deletions(-) create mode 100644 drivers/gpu/drm/vc4/vc4_txp.c -- 2.14.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
